A practical guide for high net worth individuals on valuing a portfolio that spans operating businesses, private equity, real estate and liquid investments into one clear, defensible net worth statement.
Valuing assets in isolation, at different dates and on different bases, produces a misleading picture. Banks, regulators and family members need one consolidated net worth statement on a consistent valuation date and method. This supports lending applications, Golden Visa submissions, estate planning and investment governance.
Operating businesses are valued using DCF and market multiples on normalised earnings. Private equity and fund interests are valued on net asset value with adjustments for reporting lags. Real estate is valued under RICS Red Book methodology. Listed and liquid investments are marked to market.
The most frequent errors are stale valuations, inconsistent dates, double-counting of assets held through multiple entities, and self-assessed business values that banks will not accept. An independent valuation resolves all four and gives you a figure you can defend.
How do I value my whole portfolio as one figure?
Each asset class is valued with the appropriate method on a single consistent valuation date, then consolidated and reconciled into one net worth statement. An independent valuer ensures the methods and dates are consistent.
Will a bank accept my own valuation of my business?
Generally no. Banks and regulators require an independent, certified valuation for lending, Golden Visa and compliance purposes. A self-assessed figure has no formal standing.
How often should an HNWI portfolio be revalued?
Annually for governance, or whenever a major transaction, financing, visa application or succession event requires a current, defensible figure.
